ABSTRACT:
An ergonomic writing instrument comprising a writing instrument and a shell. The shell has a longitudinal axis and opposite ends and a hollow interior. The writing instrument is positioned within the shell with its operational end extending from one end of the shell. The shell has a groove therein extending from adjacent the one end to adjacent the other end. The groove has a bottom and an upstanding wall. The groove spirals around the shell. The bottom has a width greater than the size of one's fingers. The spiral has at least two turns between the opposite ends of the shell. The bottom extends from the wall toward the other end and is tapered from one turn of the wall to an adjacent turn of the wall with the wall facing the other end whereby one can pick up the writing instrument and very easily grip the writing instrument correctly with a lighter grip than with conventional writing instruments and yet press harder while writing without the fatigue, writing cramps or calluses normally related to handwriting for long periods of time.
